技能CD減少是有極限的? - 線上

如題

剛剛在實驗幻術的幻影手槍build

突然發現神奇的事情，

就是2-IX Duelist's Discipline
6-Master Illusionists Celerity

這兩個Tarit都會讓槍4 CD -20%

http://wiki.guildwars2.com/wiki/Duelist%27s_Discipline
http://wiki.guildwars2.com/wiki/Illusionists_Celerity

可是他們同時點出來時，也只會出現-20%的效果
不管怎麼點，槍四都是16秒CD


所以請問這是-CD有極限，還是什麼原因讓這兩個Tarit不能疊?
